Went into Scotty Browns (posh ChCh bike shop) for the second time today, so I'm obviously not a regular or anything. Asked for a disk brake mount that they didn't have in stock. They handed me another one that they thought might work and said 'If it works, come back tomorrow with a packet of biscuits' and wouldn't accept any money for it. True story.

It all depends on how Upper middle class you LBS is, I started off trying to pay in posh biscuits from Waitrose, this was rejected outright, a bit of negotiation ensued and I ended up paying in Foie gras, Truffles and Quails eggs...

If I want to skip the queue for the workshop it will apparently cost extra in the form of caviar the some Prosciutto ...
